form of the invention, 10 indicates a support or Operation: The film 14 is fed m the P pedestal having joumaled therein a. shaft 11 Jection apparatus ou h the uide 15 and about upon which is fast a sprocket '12. Formed on the the Spiral feed Screw The closure P ate i8 shaft 11 is a spiral feed screw 13 onto which the slipped off Pin 4 nd the head end of the 105 film 14 is directed fro th projection apparatus film 14 is attached to'the elements 24 on one of through a guide 15. Having a hub 16 floating the members 23 on the relatively stationary reel on the shaft 11 is a casing generally indicated at ring member 21. The drive shaft 38 is then op- 17. This casing 17 has an open side 18 over erated by conventional means (not shown). which is arranged a closure plate 19. This closure Motion is transmitted from shaft 38 through the no ill! sprocket 39 and through chain 40 and sprocket 12 to rotate the shaft 11 and the feed screw 13. At the same time the motion of drive shaft 38 is transmitted through sprocket 37, chain 36, sprocket 35, shaft 34, and gears 33 and 32 to rotate reel ring 44 (clockwise Fig. 4); the ring 44 traveling in the guide portions 45 of members 23. vAs the ring 44 revolves inside the members 23 and relative to stationary ring 22, the spiral feed screw 13 feeds the film 14 into the path of movement of the yieldable film-winding elements 29, between said elements 29 and the filmretaining members 23, and the elements 29 are urged radially outwardly toward the film-retaining members 23 by springs 30; and the rollers 29 on the reel ring 44 engage the film 14 and urge the film outwardly against the film-retaining members 23, thereby winding the film inside the members 23 insuch a manner that when a length or roll of film is completely wound up inside the members 23 and tail end of the film is on the innermost winding and the head end of the film is on the outermost winding.

The cover plate 19 may then be slipped 011 pins 43 and reel 20 with the film 14 may then be removed from the casing 1'1, and placed as in Fig. 8 in a second casing 1'! which is intended to be arranged at the top of the projection machine, the first described casing 1'7 of Fig. 3 being arranged at the lower part of the projection machine. An empty reel 20 is then placed in the lower casing 17 from which the reel and film have been removed. The head end of the film on the reel 20 in the upper casing 17 is then removed from attaching elements 24 and paid out of slot 41 in the.casing through the projection machine and onto the winding device in the lower casing 1'1 as described.

By the use of my novel film-winding device in the manner hereinbefore described the step of rewinding the film and the labor and time incident thereto are thus eliminated.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. 1, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having thus described my invention what I claim as new and desire to protect by Letters Patent is:

1. A film-winding device, comprising a reel including a stationary ring member and a rotative ring member, film-retaining members projecting laterally from said stationary ring member, said film-retaining members including portions guiding said rotative ring member, said rotative ring member including radially arranged arms, film-winding elements slidably mounted on said arms, individual yieldable means on said arms urging said film-winding elements radially outwardly toward said film-retaining members, means for feeding a film into the path of movement of said film-winding elements between the same and said film-retaining members, and means for operating said feeding means and said rotative ring member.

2. A film-winding device, comprising a reel including a stationary ring member and a rotative ring member, film-retaining members projecting laterally from said stationary ring member, said film-retaining members including portions guiding said rotative ring member, said rotative ring member including radially arranged arms, film-winding elements slidably mounted on said arms, individual yieldable means on said arms urging said film-winding elements radially outwardly toward said film-retaining members, a rotative spiral feed screw for feeding a film into the path of said film-winding elements between the same and said film-retaining members, and

means for rotating said feed screw and said rotative ring member.

3. A film-winding device comprising a stationary ring member and a rotative ring including radially arranged arms, film-retaining members arranged at intervals around said stationary ring member and projecting laterally therefrom, said film-retaining members having portions guiding said rotative ring member, portions on said filmretaining members for attachment to a film, filmwinding rollers slidably mounted on said arms, individual yieldable means in said arms urging said rollers radially outwardly toward said filmretaining members, means for feeding a film into the path of movement-of said roller members between the same and said film-retaining members, and means for operating said feeding means and said rotative ring member.
